On the local news, they broadcast part of the official press conference/public info session that happened right at news time. They are saying it was an earthquake swarm - felt so strongly because they were very shallow and because our rock transmits well.
right.I'd be wondering what's coming in the next few weeks/months.
I've been dinking with the two maps, that WW posted, in Photoshop and created an overlay of the escarpment and the rift. I don't know how to post them here, I can email it to one of the mods if they want to give it a whirl. It may shed some light on a couple of things and... well seeing is believing.
K-

So if this is indeed a quake then it started Sunday night? And is still happening? So they are having quake after quake? Albeit very 'micro', but still, a quake...
The booms, according to my contacts from VaTech, are the pressures building up on the plates. The small quakes that accompany them are the smaller faults slipping a bit and adding their stresses on the main faults.
And we have been having booms and moans tonight here. Just had one about 4 minutes before I typed this.
Something is up. I had a feeling that we would "have to pay" for all of those solar blasts hitting us.
Time will tell.

By the way Red Baron....THANK YOU Good job!
I plotted (not exact since I'm doing it on a printed grid map) out the Birch Creek, MI ground fracture (loud Boom heard and felt at the time) from Oct. 2010, Clintonville and Montello, WI.
They form a nice curvature (along the same curvature of the Niagara Escarpment) just North and West of the escarpment, but between the escarpment and the rift.
Wouldn't that be logical if the escarpment acts as a point of resistance/barrier to any movement coming from the rift?

I put the following on a different forum about 6 months ago.
The past few weeks the "ground thunder" has really been bad again.
=====================================================
This may relate to all of the "ground thunder" we hear all the time.
Lots of people nearby have reported hearing it, so we're not just hearing crazy things. Sometimes we hear "popping" or "cracking" sounds coming from underground. At times we've thought it was maybe underground tunneling, but we're not so sure. This ground thunder or "booms" as we call it happens any hour of the day or night, doesn't matter if it's weekends or holidays. Sometimes it goes away for a week or two, then starts up again. It makes the neighbor's horses and cattle nervous as well.
Once in a great while we will feel a little tremor coming from a quake just North of Little Rock (Guy, AR), but not usually. Too many mountains between here and there.
We live in W AR, with the mountains and the Ouachita National Forest all around. VERY rocky area, I've got a rock partially exposed in my backyard, we can only see the top of it, and it's about the size of a Volkswagon. But it pops up here and there, doing a large basement around my yard would probably be impossible, unless blasting of this rock was involved. And if you follow my backyard down to the creek, in places this rocky area goes completely under the water and is the base of the creek. It covers an exposed area about the size of a basketball court. I told you all that in this paragraph as it makes the area where my house is built seem very stable. At least it should......
Last fall we noticed something odd in the hallway of our house. Their was a large gap between the wall and the ceiling, running about 15 feet down the hall. It was easy to see as there is corner moulding between the wall and the ceiling. The gap started out (or when we first noticed it) about 1/4" wide, but grew to over an inch in a couple month's time. It was alarming and distressing to say the least. I was in new home construction for years, and this house is only 28 years old and well built. One morning a month or so later I called my wife in there to show her something shocking - the gap was gone. The ceiling was now down on top of the wall so level, the the crack was even barely noticable.
All summer there was no change. And the booms almost seemed to stop. Well the booms started up pretty bad a couple weeks ago, darn near the same time that the quakes were being reported in Oklahoma. And last night I noticed - the crack is back, about 3/8" this time. However, now there is also a gap in my son's room and our master bedroom, and my wife is reporting "cracking sounds" in the wood (or something) in the opposite corner of our living room.
We are not alone in this, as the neighbors across the road have reported recent cracks in the blockwork of their home. And one homeowner in a town about 12 miles South of us reported the tremors, and that the water pipes outside her home keep getting pulled apart.
But.....this is not the most alarming part.
The ground outside is slowly moving. We started noticing this a few years ago, at first I wasn't sure if I was seeing things, but now I'm positive I'm not. It has moved WAY too much. The neighbor didn't notice it at first either, but now he sure has. What it appears to be doing actually, is sinking in places. Our lawn goes back about 175' behind our house, then we have a barbwire fence seperating a small field (large blackberry patch) before it hits a dirt ledge and drops down to the creek. The field always had a little downward pitch to it, before it dropped sharply down to the creek.
Our neighbor every couple years does us a favor and brush-hogs the berry patch down to ground level, as it kills off the small trees that pop up and is better for the berries to cut them back. When he did it a month ago and I walked back there, my jaw about hit the dirt. In the 160 feet or so from the barbwire to the ledge, the land has gone down at least SIX FEET. My neighbor almost rolled his tractor there, and he told me he didn't 'remember' it pitching like that. Well yeah. And it has sunk to the North and South of the house, though not as much. He noticed it on the North side last fall, when he backed his tractor up from setting off large bales of hay like he's done for years, and thought he sunk into the ground. I saw him get off the tractor, look at the ground and scratch his head. He also was looking at a large grandfather oak that is now leaning over at a bad angle.
I don't know what the heck is going on. In certain areas it could be underground tunneling, and the "booms" could be blasting the rock. But we are obviously VERY concerned. We moved here over 7 years ago, and if we compare some pics I took of the area from where we first bought here to recent pics of how the elevations have changed, whoa.
We had homeowners insurance thru Allstate, but we switched when we were told that they were dropping earthquake coverage. So at least we have coverage for that.
This is just so far out of the normal range of "stuff happens," that I'm at a loss.
And about a year and a half ago, our security light was out on the pole, about a 75' run from our main power pole. The elec. co. that maintains them came out to fix it, and he showed me that for some reason the ground between the poles swelled and bent the poles opposite of each other, and actually pulled the arial wires out of the connectors by stretching it taught, and that's why the light was out. He couldn't figure it out.
Since then that part of the ground returned to normal, and the arial wires aren't tight.
OK, I get that the ground can sink in places sometimes. Not hard to wrap my head around that.
But the fact that something tweaks my dang house, then tweaks it BACK is what is warping my mind. It moved the power poles out, stretched the wires taught - then went back.
WTF?
And it's *not* a humidity thing inside my house. The wall where the crack shows up is in the center of the home - a load-bearing wall.
During the second half of 2011, a lot of people all over the planet started reporting hearing really strange noises coming from the sky. In some instances the noises produced a loud rumbling such as a train, a thunderstorm or the slamming of a heavy door would make. In other instances, the noises sounded more like "groaning". In yet other instances the noises sounded almost as if a trumpet was playing. Dozens of videos went up on YouTube purporting to document this phenomenon, but the truth is that you can fake almost anything on a YouTube video and many dismissed these strange "strange sounds" as an Internet hoax. However, now entire towns in the northern part of the United States are hearing strange noises in the sky and the mainstream media is reporting on it. In fact, one U.S. town is planning to spend thousands of dollars to hire an engineering firm to investigate where these strange sounds are coming from. At this point a lot of theories about these strange noises are being floated, but so far scientists have not been able to give us a definitive explanation for the source of these strange noises. So exactly what in the world is going on?
The booms, according to my contacts from VaTech, are the pressures building up on the plates. The small quakes that accompany them are the smaller faults slipping a bit and adding their stresses on the main faults.

If I understood the speaker at the press conference correctly, they can prove one definite earthquake at one specific time because they had access to 8 monitors at the time of that quake. They interpolate from that that there were other earthquakes, undetected by monitors - that there was actually a swarm of earthquakes, initially undetected because there was no close monitoring of the area around Clintonville when they happened.
Well guys I guess I'll throw in my 'little bit' to help goose the paranoia along...
Clintonville WI is [roughly] 60 miles to the west of the escarpment.
Montello WI is [roughly] 60 miles west as well.
Clintonville is about 80 miles north by northeast of Montello...
About 30 miles south of Clintonville is a river called the 'Wolf River'....
Last night my son and I were talking about this whole situation...
A co-worker of his lives along the Wolf... He said the river has risen about 2 feet over the last day or so... We've had no rain and not much rain to the north of his location. This co-worker was saying... "must be an underground Glacier melting and releasing water"
Uh... Don't think so... but the question I have is: Wheres this water coming from? Could we be getting some sort of 'bulge' starting up thats squeezing the aquifer from below ? Again I doubt it... if its something like that there should be reports of water burst outs from somewhere... The Wolf is a [big] river (relatively) and to get that sort of level raising you'd need a lot of extra influx...
Anyway, just putting out another 'dot'...

The bigger question is: What if the Yellowstone Caldera is a LOT bigger than what everybody thinks it is?...

IIRC there is an "extinct" super volcano over the border in Canada not far from the UP. I'll have to go look that one up again.

On Isle Royale itself there are a number of inland lakes. (Including Chicken Bone Lake)
The great island itself is volcanic in origin, built up from lava which seeped from fissures in the earth. In fact, it is believed that the greenstone flow of lava which forms the backbone of the island is the largest volcanic flow ever known on earth.
The volcanic island was scoured by sheets of ice which moved across the island during glacial periods, creating the basis for the present day topological features.
